In the context of percent yield, what is the term used to describe the maximum possible amount of product that can be obtained from a chemical reaction, based on the limiting reactant?

• A. Theoretical yield
• B. Percent yield
• C. Actual yield
• D. Stoichiometric yield

Answer: (A)

Verified step by step guidance

1. Understand that in a chemical reaction, the amount of product formed depends on the reactants and their quantities.
2. Identify the limiting reactant, which is the reactant that is completely consumed first and thus limits the amount of product formed.
3. The maximum possible amount of product that can be formed from the limiting reactant, assuming perfect reaction conditions and complete conversion, is called the theoretical yield.
4. Percent yield is calculated by comparing the actual yield (the amount of product actually obtained) to the theoretical yield using the formula: \(\text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100\%\).
5. Therefore, the term describing the maximum possible product amount based on the limiting reactant is the theoretical yield.
